Madison Boyd

Registered Dental Assistant

Amanda Evans, Front Desk

Madison is a graduate of the Concorde Career College where she completed her degree with a perfect 4.0 GPA, finishing Magna Cum Laude.

As a dental assistant, her job is to provide clinical treatment for patients chairside with Dr. Rottman as well as make sure they are completely comfortable and well-informed during their appointments. She absolutely loves what she does, and in her own words, “I give 120% every day. Getting to know people one-on-one is something I look forward to.” She likes how the small staff makes it easier for her to form deeper relationships with patients, and she enjoys the opportunity to work closely with Dr. Rottman, who she considers a great physician and friendly person.

Away from the office, most of her time is spent with her young son. Together, they like to regularly participate in agricultural shows with her son’s prized cow, Hank.


Liana McArdle

Registered Dental Assistant

Liana McArdle, Registered Dental Assistant

Liana first joined our team in June of 2019, and her overall career in the dental field spans over a full decade. She graduated from the Certified Dental Assisting Program at Western Career College in Sacramento with a 4.0 GPA and also received the Volunteer Excellence Award through the new student mentoring program, where she guided students who were showing signs of struggle.

As an assistant, Liana helps Dr. Rottman with clinical treatments, educates patients about the value of oral hygiene, and makes sure that they have a relaxing environment for necessary treatment. She loves working here because of the wonderful patients and the amazing team members! Everyone is so kind and always ready to help out with day-to-day tasks. It feels like a tight-knit family here at Sachse Family Dentistry and she wouldn’t ask for it any other way. She feels passionate about changing the stereotype of a “scary” dental office and helping patients escape from that mind frame. Her motto is: “We are here to help you, not hurt you!” 

Liana and her husband are high school sweethearts, and they have a small zoo at home that includes three dogs, two cats, and a “reptile room” with two bearded dragons, one flowerhorn fish, and two tarantulas. Outside of work, her favorite activities include snowboarding, playing piano, and maintaining her flower and vegetable gardens.

Additionally, she performs oral cancer screenings, intraoral radiographs, topical fluoride administration, dental sealant application, and much more. She prides herself on being gentle and caring in the practice while also giving each visitor the best experience possible! She is additionally very grateful to work with Dr. Rottman, who is an amazing, personable, and conservative dentist. Everybody in the practice goes and beyond – it’s an amazing place to work, and she wouldn’t let her family and friends go anywhere else.
